American zoologist. doi:10.1668/0003-1569(2001)041[0219:tiecif]2.0.co;2More infoThe earliest studies of intermittent exercise physiology noted that moving intermittently (i.e., alternating brief movements with brief pauses) could transform a heavy workload into a submaximal one that can be tolerated and sustained. The brief pauses that characterize intermittent locomotion permit at least partial recovery from prior activity. This research provided the foundation for the development of interval training and more recently for the re-evaluation of steady-state paradigms for comparative animal locomotion. In this paper I review key concepts underlying the performance of repeated activity. I provide examples from human athletics and training and comparative animal locomotion. To explore the limits of intermittent exercise performance, I examine the performance limits for continuous exercise and the rate and extent of the recovery of performance capacity following activity. While it is evident that altering locomotor behavior (i.e., moving intermittently) can alter the capacity of an animal to perform work, mathematical models of intermittent exercise could predict strategies (i.e., exercise intensity, exercise duration, and pause duration) that will increase performance limits for intermittent activity.
- Weinstein, R. B. (1998). Effects of Temperature and Water Loss on Terrestrial Locomotor Performance in Land Crabs: Integrating Laboratory and Field Studies. American zoologist. doi:10.1093/icb/38.3.518More infoSYNOPSIS. Terrestrial and semi-terrestrial crustaceans are exposed to fluctuations in ambient temperature and conditions that favor evaporative water loss. These environmental stresses alter performance limits in the laboratory and behavior in the field. The maximal rate of oxygen consumption, maximum aerobic speed, and endurance capacity are greater at a body temperature (Tb) of 24°C than at 15°C or 30°C in the ghost crab, Ocypode quadrata . The total metabolic cost to move at the same relative speed is greater at a Tb of 24°C than at 15°C. Slower aerobic kinetics at 15°C result in a smaller relative contribution of oxidative metabolism to total metabolic cost. However, the relative contributions from accelerated glycolysis are similar at both temperatures. When locomotion is intermittent, the total distance traveled before fatigue can be similar at Tbs of 15 and 24°C but result from different movement and pause durations at these temperatures. Performance limits of the ghost crab are negatively affected by dehydration and are sensitive to rates of water loss. In the laboratory, endurance capacity of the fiddler crab, Uca pugilator, is greater at a Tb of 30°C than at 25°C. In the field, freely moving fiddler crabs with a Tb of 30°C travel at faster mean preferred speeds, as determined by motion analysis, than crabs at 25°C. Data for land crabs support and advance general ectothermic models for the effects of temperature and dehydration on locomotor performance.
